This invention pertains to tobacco pipes embodying radiating or cooling surfaces and condensing surfaces by which tar, oil andm'oisture are separated and trapped.

The object of the invention is to improve the construction, as well as the means and mode of assembly and operation of smoking pipes, whereby they may not only be economically manufactured, but will be more eflicien't in use, having relatively few parts of simple construction and be unlikely to get out of repair.

Another object of the invention is to provide a smoking pipe having maximum radiating sur' faces capable of dissipating the heat of coinbustion both inwardly and outwardly.

A further object of the invention is the provision in a smoking pipe of a condensing surface whichis easily accessible for cleaning.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letter Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

In the accompanying drawings wherein is illustrated the preferred, but obviously not the only form of embodiment of the invention,

Fig. 1 is a side elevation of an assembled smoking pipe embodying the present invention.

Fig. 2 is an end elevation thereof from the right of Fig. 1. L

Fig. 3 is a longitudinal sectional view of the assembled pipe. i

Fig. 4 is a cross sectional view taken on line 4-4 of Fig. 3.

Fig. 5 is a side elevation of the inner radiating tube and condenser removed from the assembly.

Fig. 6 is a plan view of the bit, forming the mouth piece of the stem.

Like parts are indicated by similar characters of reference throughout the several views. The present pipe comprises essentially the tobacco receiving bowl I, the stem 2, and bit or mouth piece 3. The bowl may be of any shape or size. The stem 2 includes a tapered or conical tubular outer member or sleeve 4, of heat conductive material preferably but not necessarily aluminum, having a series of radially disposed longitudinal fins or ribs 5.

Disposed axially within the tapered outer member 4 is an inner radiator and condenser tube 6 carried by a plug 1 which is detachably positioned in the outer end of the tapered cuter tu- 1, iclaims'. (o1. 131-194) bular member 4, and provided at its inner end with screw threads 8 engageable in corresponding internal crew threads in the smaller end of the outer tapered tubular member 4. There is thus formed an intermediate smoke passage 9 with the larger end of which the tobacco bowl communicates.

The bore of the inner tubular member 6 is closed or plugged by a divider wall In adjacent its inner end, dividing the bore thereof into a longer portion or chamber II which communicates through the plug 1 with atmosphere only, and a shorter portion or chamber l2 having a lateral port l3 formed therein through which it communicates with the passage 9, formed intermediate the tapered tubular member 4 and the inner tubular member 6.

The bit or mouth piece 3 is provided with a reduced extension [4 which has a sliding fitwithin the shorter portion or chamber I2 of the bore of the inner tubular member 6. This extension is provided with a lateral port I5 which communicates with the usual axial passage there-, through shown at I6. The lateral port I5 registers with the port l3 in the shorter portion or chamber of the inner tubular member 6 when the parts are assembled and the bit is rotatively adj usted to its position for use. However by a slight partial rotation of the bit 3 with respect to the inner tubular member the ports [3 and 15 are relatively shifted out of registry thereby limiting or preventing passage of moisture and con densate through the bit passage l6.

,In operation the smoke and heated products of combustion drawn from the bowl I into the passage 9 impinge upon the top area of the axially disposed inner tubular member 6. The heat communicated to the outer conical member 4 is dissipated by the external ribs or fins 5. The interior compartment ll of the inner tubular member 6 being open to atmosphere at its end is comparatively cool, and not only absorbs and transmits to the atmosphere a part of the heat of combustion but it also serves as a condensing surface to receive tar, oil and moisture distillate which collect to a greater degree along the top of the inner tubular member 6. The heated products of combustion striking the top of the inner tubular member 6 expand the air within the compartment II thereof causing displacement of air therefrom to the atmosphere. The subsequent reduction of temperature and consequent contraction of the air content of the compartment ll draws into the tube compartment H through its open end a small charge of cool air 7 acter described .possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages. 7 7

While the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown,

but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimateand valid scope of the appended claims.

Having thus described my invention, I claim:

1. In a smoking device having a tobacco receptacle and a mouthpiece provided with an extension, a support therefor, including a tapered hollow sleeve, with which. the receptacle and mouthpiece communicate in spaced relation with respect to each other, an annular plug supported within the end of the sleeve adjacent the receptacle, 2. heat exchange and condensate collecting tube carried by the annular plug in removably positioned alignment with the mouthpiece within the sleeve, a portion of the interior of said tube being open to the atmosphere only through the plug, a separator wall in said tube adjacent the opposite end thereof, said opposite end being closed by the mouthpiece which is telescoplcally supported therein, and communicating lateral ports in the said opposite end of the con- -of the condenser tube including an extension projecting within the tube, lateral ports in the mouthpiece extension and the condenser tube rotatably adjustable into and out of registry which when in registry permit communication of the mouthpiece with the tobacco receptacle through the stem, and a separator wall in said tube dividing the interior thereof into a first chamber receiving said mouthpiece and a second chamber communicating with atmosphere.

3. In a smoking device having a tobacco receptacle and a mouthpiece, a hollow sleeve interposed therebetween upon which the tobacco receptacle is supported in communicating relation with the interior thereof, a heat exchange and condensate collecting tubular member concentrically disposed within the sleeve, means for supporting said tube at opposite ends of the sleeve, one end of said tube being closed by the mouthpiece, within which tube the mouthpiece is supported, the opposite end of the tube being open to atmosphere only, a smoke chamber formed intermediate the tube and the interior of the sleeve, and aligned lateral ports in said tube and mouthpiece interconnecting the smoke chamber with the mouthpiece.

4. A smoking device, including a tapered hollow stem, a tobacco receptacle mounted on the large end of said stem and communicating with the interior thereof, a plug having a longitudinal through opening therein mounted in th large end of said stem, an open ended heat exchange and condensate collecting tube axially disposed in said stem with its one end received in the longitudinal opening in said plug and with its other end in screw threaded connection with the small end of said stem, said tube defining with said stem an annular smoke chamber diminishing in size toward the small end of said stem, a mouthpiece formed with a shoulder to abut the small end of the stemand a tubular projection received in and closing the adjacent end of said tube, and lateral aligned ports in said tube and the tubular projection on said mouthpiece located adjacent the vanishing point of said smoke chamher to connect said chamber to said mouthpiece.
